Roman Catechism 6.3

Chapter 6 — Part I: The Creed — Article IV: Suffered Under Pontius Pilate, Was Crucified, Dead, and Buried

Section 3. "Suffered," — It cannot be a matter of doubt that His soul" as to its inferior part" was sensible of these torments; for as He really assumed human nature" it is a necessary consequence that He really, and in His soul, experienced a most acute sense of pain. Hence these words of the Saviour: My soul is sorrowful even unto death.
